Are there any plans for non-US/UK courses from the European Tour or further afield?
No one knows what WGT has planned, and they usually don't say. Considering the travel costs required, probably not.
For a time WGT had an agreement with the Royal and Ancient, but not since Royal St. Georges was added several years ago.
After RSG it was said that the next Open venue (Lytham) would have to be skipped (?due to contractual issues?). It has stayed so ever since.
Shame since everyone loves UK courses
